DISK-CLUTCH TRANSMISSION.

To all whom it may concern:

Be it known that I, WALTE L. FEE, a citizen of the United States,residing at M01 line, in the county of Rock Island, State of Illinois,have invented certain new and useful Improvements in Disk-ClutchTransmissions; and I do hereby declare the following to be a full,clear, and exact.description of the invention, such as will enableothers skilled in the art to which it appertains to "make and use thesame.

This invention relates to clutch devices for transmissions.

The object oiKthe invention is to provide a device of the characternamed which will be simple in construction, efficient in use andcomparatively inexpensiveto manufacture and maintain.

With the above objects in view the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understoodthat various modificationsmay-be made in the minor details ofconstruction within the scope of theappended claim.

In the accompanying drawing illustrating this invention :Figure 1 is aplan view of my improved transmission. Fig. 2 is an enlarged plan viewshowinga portion of the transmission with. one of the'clutches inoperative position. Fig.-3 is a longitudinal sectional View on the line3-3 of Fig. 1.

Fig. 1 is a cross sectional view on the line 4-4 Fig. 1. Fig. 5 is across sectional view on the line 5-5 Fig. 1, Fig. 6 is a fragmentarydetail view-showing the link motion for operating one of the clutches.

Referring now to the drawing in which like characters of referencedesignate simi lar parts, 10 designates a shaft which ismounted inabearing 11 and one end of a casing 11' and is driven inany preferredmanner from the engine. Extending parallel with the shaft 10 is a shaft13 that is driven from the shaft 10 as will be presently described. andis mounted in a bearing 14: and in the ends of the casing 11 as shown,this driven shaft being operatively connected to the drive wheels of themachine in the usualmanner. V

The driving shaft 10 and driven shaft 13 are operatively connectedtogether at vari ous points through the instrumentality of novel clutchgear connections, A indicating the high speed gear connection, B the lowSpecification of Letters Patent.

' Application filed January 22, 1914. Serial No. 813,794.

' nection, any particular gear connection being thrown into activeposition to transmit the motion of the driving shaft to the driven.shaft at a desired speed and in a desired direction as usual.

For brevity and clearness, but one of the clutch gear connections willbe described in detail, since the remaining clutch gear connections arecounterpart of the one described. Each clutch gear connection comprisesa gear 15 keyed on the driving shaft 10, a. gear '16 loose on the drivenshaft 13, there being a clutch disk 17 keyed on the driven shaft and onone side of the loose gear and there being a clutch disk 18 slidablyfitted onthe driven shaft on the opposite side of the loose gear.Helicalsprings 19 and 20 are seated on the driven shaft between theloose gear aiid the clutch disks to prevent accidental engagement of thedisks with the gear.

A disk 21 is keyed on the driven shaft and is provided on one face withguide pins 22 upon which telescope tubes 23 carried by the clutch disk18. Levers 24s are pivoted on the periphery of the disk 21 and links 25are pivoted to these levers and, to the disk 18. Upon the link leversbeing rocked outwardly the angle between the levers and the relatedlinks will be straightened whereby the links serve to move thin disk 18up against the loose gear 1(3with a resultant binding of. the latteragainst the disk 17 whereby the loose gear'is locked for rotation withand drives the driven shaft. By virtue of the loose gear being always inmesh with the gear 15 the clutch will become active the instant theclutch disk 18 binds the loose gear against the clutch disk 17 so that apositive and quick acting clutch and at the -same time a noiselessclutch is produced.

The free front speeds A, B and D are identical, and the abovedescription suffices 'for all, but the reverse speed includes theprovision of an intermediate gear 26 between the driving gear 15 anddriven gear 16 whereby the direction of rotation of the shaft 10 istransmitted reversed to the shaft 13 as will be understood. For shiftingthe clutch gear transmissions selectively into active or releasedposition, I provide ablock 27 that is slidably mounted on the drivenshaft between adjacent clutch gear transmissions as shown and is pro-"vided with peripheral pivotal links 28 which are connected to therelated levers 24c, and i the block is provided with a shifting yokelever 29.

Journaled in the casing 11 is a sleeve 30 and rotatable in the sleeve 30is a shaft 31.

I Mounted on the end of the sleeve 30 disposed within the casing 11 isan arm 32, while another arm 33 is mounted on the end of the shaft 31which is disposed in ;said casing. These arms 32 and 33 are connectedrespectively to the yoke levers 29.

Mounted on the outer end of the sleeve 30 is an arm 34 the free end ofwhich is provided with a lateral extension 35. Mounted the dircctioninwhich the lever is flexed.

[By engaging these extensions 35 and 37 selectively 1n the passage 39 itwill be obvious that the lever 38 can be operated to throw any of thetransmissions into active position.

From the abovedescription it will be seen that I have provided anextremely simple and efiective clutch gear transmission that will bequick acting and noiseless and Will fixed on the shaft; on one side ofthe memher, a second friction disk slidable on the shaft on the otherside of the member, spring means interposed between the member and eachdisk for normally holding said ,disks out of operative relation to themember, and means for moving the splined disk against the member to inturn force the lat ter against the fixed disk and whereby the member islocked to both of said disks, said means comprising socketed projectionson the outer side of the second named friction disk, a member slidableonsaid shaft and having project-ions thereonslidable in respectivesockets of the projections, levers pivoted on said member atdiametrically 0pposite points, links connecting corresponding ends ofsaid levers With the second named friction disk, and means for rockingsaid levers to slide the friction disk on the shaft;

In testimony whereof, I affix my signature, in the presence of twoWitnesses. WALTER LFEE.
